MILAN, June 30 (Reuters) - Italy's top four insurers and Germany's Allianz (ALVG.DE) have agreed a multi-billion euro rescue deal for Eurovita, industry supervisor IVASS said on Friday after months of work to broker an accord which also involves 25 banks. Earlier this year, Eurovita became the first Italian insurance company to be placed under special administration, after running into trouble due to higher interest rates. Insurers Generali (GASI.MI), Intesa Sanpaolo Vita (PST.MI), Poste Vita (PST.MI), UnipolSAI (US.MI) and Allianz will set up a new company that will take on Eurovita life insurance policies. To prevent the five insurers from being hit by redemptions once the ban is lifted, banks that sold Eurovita the products are participating in the rescue. The lenders will provide financing to repay Eurovita customers who redeem their policies, while holding the underlying bonds to maturity and neutralising any losses.
